Mandevilla plant named ‘Lanarizona’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Lanarizona’, characterized by its upright and vining plant habit; vigorous growth habit; large glossy dark green-colored leaves; early and freely flowering habit; and large white-colored flowers.

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘LANARIZONA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Lanarizona’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Malause, France. The objective of the breeding program is to create new uniform and early-flowering Mandevilla plants with numerous attractive flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France on Jul. 14, 2005 of (Mandevilla×amabilis)×Mandevilla splendens ‘PSJAM DP1’, disclosed in U.S. Plant Pat. No. 10,413, as the female, or seed parent with Mandevilla Sanderi ‘Blanc’, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Malause, France in November, 2007.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Malause, France, since May, 2010 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lanarizona’. These characteristics in combination distinguish ‘Lanarizona’ as a new and distinct Mandevilla plant:

-   -   1. Upright and vining plant habit.     -   2. Vigorous growth habit.     -   3. Large glossy dark green-colored leaves.     -   4. Early and freely flowering habit.     -   5. Large round white-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent, ‘PSJAM DP1’. Plants of the new Mandevilla differ primarily from plants of ‘PSJAM DP 1’ in the following characteristics:

-   -   1. Plants of the new Mandevilla have larger and flatter leaves         than plants of ‘PSJAM DP1’.     -   2. Plants of the new Mandevilla have larger flowers than plants         of ‘PSJAM DP1’.     -   3. Plants of the new Mandevilla and ‘PSJAM DP1’ differ in flower         color as plants of ‘PSJAM DP1’ have deep pink-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent, ‘Blanc’. Plants of the new Mandevilla differ primarily from plants of ‘Blanc’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vigorous than plants of         ‘Blanc’.     -   2. Plants of the new Mandevilla have larger and darker         green-colored leaves than plants of ‘Blanc’.     -   3. Plants of the new Mandevilla have larger flowers than plants         of ‘Blanc’.

Plants of the new Mandevilla can be compared to plants of selections of Mandevilla×amabilis known to the Inventor, not patented. In side-by-side comparisons conducted in Malause, France, plants of the new Mandevilla differed from plants of selections of Mandevilla×amabilis known to the Inventor in the following characteristics:

-   -   1. Plants of the new Mandevilla had larger, flatter and darker         green-colored leaves than plants of selections of         Mandevilla×amabilis known to the Inventor.     -   2. Plants of the new Mandevilla flowered about two weeks earlier         than plants of selections of Mandevilla×amabilis known to the         Inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Mandevilla plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Mandevilla plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Lanarizona’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in 27-cm containers in polyethylene-covered greenhouse in Malause, France and under cultural practices typical of Mandevilla commercial production. During the production of the plants, day temperatures ranged from 8° C. to 26° C. and night temperatures ranged from 3° C. to 15° C. Plants were one year old when the photographs and description were taken.
